Fragmented Glass Measuring System

Optifrag, winner of the FEDIL innovation prize in the category ''SME''

 

What’s more, the quality and quantity of data generated by the computer-based process offers a unique insight into the tempering process that cannot be achieved using a traditional method.

The OptiFrag station uses the ECE R43 standard as its framework for analysis, but can include any other international standard, providing a unique comprehensive result report that immediately includes all requested tests

The OPTIFRAG audit station quantifies glass fragments through advanced phase shifting deflectometry, a process which analyses the light reflected by the fragmented surface.

This technology introduces significant improvements over legacy solutions as it eliminates the current need for photosensitive paper film, and allows the measurement of fragments directly on the inspected surface, including tinted glass and areas with serigraphy.

Furthermore, the results are not impacted by defrosting wires, or folds in the plastic film (often used to maintain the fragments in place). In addition, the computerized process encourages cost-savings by migrating the storage of results from physical to digital archives.

Traditional Method :
Manual fragment counting on paper film

Following 5 decades of technological stagnation, VIRELUX revolutionized fragmentation testing. Introducing digital automation to an outdated manual process.

OptiFrag Equipment :
Automated measurements directly on the surface of the inspected glass

OptiFrag System

Traditional Method

Objective, repeatable measurements

Complete measurement cycle time of
less than 3 minutes

Tinted areas = measurable

Serigraphy areas = measurable

Defrosting wires = no impact

No photosensitive film & ammoniac-based development process required

Total Fragment Count

Statistical exploitation of results

Inexpensive digital archiving

Comprehensive report of all measured standards

Density map of the entire glass allows unique insight into the tempering process

Subjective measurements

Complete measurement cycle time of
more than 15 minutes

Tinted areas = not measurable

Serigraphy areas = not measurable

Defrosting wires = create false segments

Only localized manual fragment count

No digital statistical exploitation of results

Bulky & expensive physical archiving

Each standard must be measured & verified individually

No density map & information of the tempering process

Automated Measurements

Manual Measurements

Metrology-based

Transmission-based

Digital Results

Paper-based Results

Photosensitive film mandatory, but dwindling world production creates an unsustainable product dependency
